This is a recently finished commission for Universe/Classic Inferno. Inside his chest is the electronics/LED for his light bar (read headache to build so that they blink independently)
He was painted with lacquers (HOK:KK) and Testors enamels (MM) Ladder courtesy of tfctoys (gear of war set)
good question, never really thought of them as lights, but that can work. Always thought they were ladders given their shape, but would be slightly too small in scale w/ the rest of the alt mode, huh...
Not really. Could just be small ladders designed to help them get on the top of the truck. But now that it's mentioned, they could be a series of tail lights, too.
